This application claims the priority of Chinese Patent Application No. 201710301333.1, filed in China on May 2, 2017, the entire contents of which are incorporated herein by reference.

[Technical Field]

TECHNICAL FIELD The present disclosure relates to the field of communications, and more particularly, to a downlink channel transmission and reception method, apparatus, base station and terminal.

The mobile Internet is overturning the traditional telecommunications service mode, providing users with an unprecedented experience and seriously affecting people's work and life. Further advances in the mobile Internet will result in growth exceeding 1,000 times the future of mobile traffic, and will drive the transformation of new rounds in mobile communications technology and industry. The Internet of Things expands the range of services in mobile communications, extending from human and human communications to intelligent interconnection of humans and things, things and things, allowing mobile communications technology to penetrate a wider range of industries and sectors. In addition, massive device connectivity and diversified IoT services also present new technology challenges for mobile communications.

As new service demands continue to emerge and become more abundant, for future mobile communication systems, for example, higher peak rates, better user experience rates, lower delays, higher reliability, higher spectral efficiency and higher energy consumption efficiency. Higher performance is required. In addition, they must support more user connections and use a variety of service types. In order to support a large variety of terminal connections and different service types, the flexible configuration of uplink downlink resources has become one of the great trends of technology development. The system resources of the future may be divided into different subbands according to different services, and may partition transmission time intervals (abbreviated as TTIs) having different lengths on the subbands to satisfy various service demands. .

The related LTE FDD system uses a frame structure (frame structure type 1, abbreviated as 'FS1'). In FDD systems, uplink and downlink transmissions use different carrier frequencies, and both uplink and downlink transmissions use the same frame structure. On each carrier, one 10 ms-long radio frame includes 10 1 ms subframes, each subframe divided into two 0.5 ms-long time slots. The TTI time length of the uplink and downlink data transmissions is 1 ms.

The associated LTE TDD system uses a frame structure (frame structure type 2, abbreviated as 'FS2'). In a TDD system, uplink and downlink transmissions use different subframes or different time slots on the same frequency. Each 10ms radio frame in FS2 consists of two 5ms half frames, and each half frame contains five 1ms-long subframes. Subframes in FS2 are classified into three types: downlink subframe, uplink subframe, and special subframe, each half frame having at least one downlink subframe and at least one uplink subframe, and a maximum One special subframe is included.

The physical downlink control channel (PDCCH) of the LTE system is for bearing scheduling information and other control information. There may be a plurality of PDCCHs in a control region of each downlink subframe, and the size of the control region is determined by a physical control format indicator channel (PCFICH). Transmission of one control channel occupies one control channel element (CCE) or a plurality of contiguous CCEs, and each CCE is composed of nine resource element groups (REGs). The UE monitors a set of PDCCH candidates in a non-DRX subframe, that is, decodes each PDCCH in the search space according to the downlink control information format DCI (downlink control information) format to be monitored. Try.

In order to expand the capacity of the PDCCH, EPDCCH (Enhanced Physical Downlink Control Channel) was introduced in Rel-11. The EPDCCH is transmitted in the data region in the subframe and does not occupy the transmission space of the PDCCH. The terminal configured with the EPDCCH detects and receives the EPDCCH in the physical resource block set PRB (Physical Resource Block) set configured in each subframe.

In a related LTE system, the TTI length is fixed to 1 ms, and one or a plurality of PDCCHs are transmitted on the front N OFDM codes of each TTI, or on a group of physical resource block pairs (PRB pairs) of the data area. Or on a plurality of consecutive / discontinuous subframes. The UE detects its PDCCH as blind in the Common Search Space (CSS) or the UE Specific Search Space (USS) based on the information desired to be acquired. In future mobile communication systems, a group common physical downlink control channel (group common PDCCH) for scheduling or notifying a group of terminal related information should be introduced. However, at present, there is no clear solution on how to transmit the group common PDCCH for scheduling or notifying a group of UE-related information, so the UE does not know how to receive the group common PDCCH.

The technical problem to be solved by the present disclosure is to provide a downlink channel transmission method, a downlink channel reception method, an apparatus, a base station and a terminal, and how to group or group common PDCCH for scheduling or notifying a group of terminal-related information in the related art.

This can be determined by the data valid time of the channel.

Hereinafter, a specific application flow according to an embodiment of the present disclosure will be described as follows, for example.

It is assumed that the base station configures a group common PDCCH that the terminal should detect and receive by high layer signaling. For example, UEs UE1, UE2, and UE3 must detect and receive group common PDCCH1, and UEs UE4 and UE5 must detect and receive group common PDCCH2. Assuming that the base station determines that the group common PDCCH is transmitted in slot S, slot S + N, slot S + 2N, ... according to the protocol, the terminal determines slot S, slot S + N, slot S + 2N by protocol. , And ... to detect and receive the corresponding group common PDCCH. For example, assuming S = 0, the UE should detect and receive the group common PDCCH in slots such as slot 0, slot N, slot 2N, slot 3N, and the like. As shown in Fig. 2, UEs UE1, UE2, and UE3 must detect and receive the corresponding group common PDCCH1 in slots such as slot 0, slot N, slot 2N, and the like; UE UE4 and UE5 should detect and receive a group common PDCCH2 corresponding to a slot such as slot 0, slot N, slot 2N, or the like.

After receiving the group common PDCCH, the terminal transmits and receives data according to the received group common PDCCH until the next group common PDCCH receiving slot. Or, after receiving the group common PDCCH, the terminal transmits and receives data according to the successfully received group common PDCCH until the next successful reception of the group common PDCCH. Or, after receiving the group common PDCCH, the terminal transmits and receives data according to the successfully received group common PDCCH until the base station notifies to change the related parameter.

Further, if the slot to which the group common PDCCH should be transmitted is uplink-only, the base station may select to transmit the group common PDCCH in the first downlink slot after the slot. When the UE finds that the slot in which one group common PDCCH transmission location is located is uplink-only, the UE detects and receives the group common PDCCH in the first downlink slot after the slot. For example, when the base station notifies the terminal that slot N is an uplink-only slot, the base station does not transmit the group common PDCCH in slot N, and the terminal also does not detect and receive the group common PDCCH in slot N. As shown in FIG. 3, assuming that the nearest one slot including downlink resources after slot N is slot N + 2, the base station transmits a group common PDCCH in slot N + 2, and the terminal slot N + In step 2, the group common PDCCH is detected and received.

Hereinafter, another specific application flow according to an embodiment of the present disclosure will be described as follows, for example.

It is assumed that the base station configures a group common PDCCH that the terminal should detect and receive by high layer signaling. For example, UEs UE1, UE2, and UE3 must detect and receive group common PDCCH1, and UEs UE4 and UE5 must detect and receive group common PDCCH2. The base station notifies the terminal of the transmission location of the group common PDCCH by broadcast signaling.

For example, assuming S = 0, the UE should detect and receive the group common PDCCH in slots such as slot 0, slot N, slot 2N, slot 3N, and the like. As shown in Fig. 2, UEs UE1, UE2, and UE3 should detect and receive the corresponding group common PDCCH1 in slots such as slot 0, slot N, slot 2N, etc .; UE UE4 and UE5 should detect and receive a group common PDCCH2 corresponding to a slot such as slot 0, slot N, slot 2N, or the like.

When the UE finds that the slot in which one group common PDCCH transmission location is located is uplink-only, the UE detects and receives the group common PDCCH in the first downlink slot after the slot. For example, when the base station notifies the terminal that slot N is an uplink-only slot, the base station does not transmit the group common PDCCH in slot N, and the terminal also does not detect and receive the group common PDCCH in slot N. As shown in FIG. 3, assuming that the nearest one slot including downlink resources after slot N is slot N + 2, the base station transmits a group common PDCCH in slot N + 2, and the terminal slot N + In step 2, the group common PDCCH is detected and received.

For example, when the base station notifies the terminal that slot N is an uplink-only slot, the base station does not transmit the group common PDCCH in slot N, and the terminal also does not detect and receive the group common PDCCH in slot N. As shown in FIG. 3, assuming that the nearest one slot including downlink resources after slot N is slot N + 2, the base station transmits a group common PDCCH in slot N + 2, and the terminal slot N + In step 2, the group common PDCCH is detected and received.
